Chithunzi Chodziwika cha RDU5 Series(SPD)

Mndandanda wa RDU5 (SPD)

RDU5 Series SPD imagwiritsidwa ntchito makamaka pamagetsi a TN-C, TN-S, TT, IT ndi ena okhala ndi AC50Hz/60Hz, mphamvu yotulutsa mphamvu ya 5kA~60kA, mphamvu yotulutsa mphamvu ya 10kA~100kA, mphamvu yogwiritsira ntchito ya 220V/380V ndi pansi pake, ili ndi chitetezo choletsa mphezi ya gridi pamagetsi ndi mphamvu yotuluka pamagetsi.

Ndi chipangizo choteteza mphezi chopangidwa motsatira zofunikira za mayeso a SPD level l, chomwe chingagwiritsidwe ntchito poteteza zida zonyamula katundu pazingwe zamagetsi pamlingo woyamba ndi wachiwiri. Zonsezi zimapangitsa kuti zikhale zoyenera kupititsa patsogolo zofunikira zotetezera m'nyumba, mayendedwe, magetsi, masukulu apamwamba, ndi mafakitale.

Zitsanzo ndi Kapangidwe

Miyeso

Kugwiritsa ntchito

1.Miyezo: IEC61643-1 ndi GB/T18802.1

2. Kuthamanga kwa mphezi kwambiri komanso mphamvu yotulutsa madzi, mphamvu yamagetsi ya gawo limodzi mpaka 25KA(s)

3. Imagwiritsidwa ntchito kwambiri pa gawo loyamba la chitetezo cha mphezi pamakina a zida m'malo omwe mphezi zimakhala zoopsa kwambiri.

4. Ndi mawaya amkati, kapangidwe kake konse ndi kakang'ono, kosavuta kukhazikitsa mawaya

5. Yankho lachangu kwambiri, nthawi yochitapo kanthu mwachangu

6. Mkhalidwe wa ntchito ndi woonekeratu, wobiriwira (wabwinobwino), wofiira (Wolakwika)
